Displasia fibrosa maxilar. Del diagnóstico al tratamiento. Reporte de caso / Maxillary fibrous dysplasia. From diagnosis to treatment: Case report / Displasia fibrosa maxilar. Do diagnóstico ao tratamento: Relato de caso

La displasia fibrosa se puede presentar, en cualquier persona, por una mutación en los primeros meses de gestación. Se trata de lesiones óseas benignas en pacientes jóvenes, en las que el tejido óseo normal es sustituido por tejido conectivo fibroso, debido a una alteración funcional de las células, siendo esta la antesala de una neoplasia. El objetivo de éste artículo es presentar un caso local de Displasia Fibrosa Maxilar, enfatizando el manejo clínico, radiográfico, pre y postoperatorio más pertinente. Por lo tanto, se describe el caso de un paciente adolescente de género masculino, afectado por displasia fibrosa en hemimaxilar derecho, a quien le fueron realizados los estudios imagenológicos e histopatológicos necesarios para obtener el diagnóstico definitivo y decidir el abordaje menos invasivo posible cumpliendo con estándares de estética facial; se realizó abordaje intrabucal para shaving óseo, con sedación consciente bajo estricta vigilancia de la especialista en anestesiología y reanimación. Una vez logrado el contorno deseado mediante el uso de piezas de mano de alta y baja velocidad, se realizó la sutura de los tejidos y el paciente egresó ambulante y con buen estado general de salud.

Fibrous dysplasia can occur in any person due to a mutation in the first months of gestation. These are benign bone lesions in young patients, in which the normal bone tissue is replaced by fibrous connective tissue, due to a functional alteration of the cells, being this the prelude to a neoplasm. The aim of this article is to present a local case of Maxillary Fibrous Dysplasia, emphasizing the most relevant clinical, radiographic, pre and postoperative management. Therefore, we describe the case of an adolescent male patient, affected by fibrous dysplasia in the right hemimaxillary, who underwent the necessary imaging and histopathological studies to obtain the definitive diagnosis and decide the least invasive approach possible in compliance with facial aesthetic standards; an intraoral approach was performed for bone shaving, with conscious sedation under strict supervision of the specialist in anesthesiology and resuscitation. Once the desired contour was achieved through the use of high and low speed handpieces, the tissues were sutured and the patient was discharged ambulatory and in good general health.

São lesões ósseas benignas em pacientes jovens, nas quais o tecido ósseo normal é substituído por tecido conjuntivo fibroso, devido a uma alteração funcional das células, sendo esse o prelúdio de uma neoplasia. O objetivo deste artigo é apresentar um caso local de Displasia Fibrosa Maxilar, enfatizando o manejo clínico, radiográfico, pré e pós-operatório mais pertinente. Portanto, descrevemos o caso de um paciente adolescente do sexo masculino, afetado por displasia fibrosa no hemimaxilar direito, que foi submetido aos exames de imagem e histopatológicos necessários para obter um diagnóstico definitivo e decidir sobre a abordagem menos invasiva possível, em conformidade com os padrões estéticos faciais; foi realizada uma abordagem intraoral para raspagem óssea, com sedação consciente sob estrita supervisão do especialista em anestesiologia e ressuscitação. Depois que o contorno desejado foi obtido com o uso de peças de mão de alta e baixa velocidade, os tecidos foram suturados e o paciente recebeu alta ambulatorial em bom estado geral de saúde.

Use of a Community Engagement and Research Core model to enhance primary care provider recruitment: A case example.

Persistent barriers exist to engage rural providers in research and training. Provider shortages exacerbate these challenges, leading to a scarcity of time and limiting motivation to participate in research. We present application of an innovative engagement model to increase rural primary care provider participation in research. Using our Community Engagement and Research Core, we demonstrate that fundamental principles of training and expertise, attention to efficiency and multitasking, and commitment to community are important for addressing provider recruitment barriers. We encourage other Clinical and Translational Science Centers to provide similar services to their local investigators to enhance provider engagement in research.

Effects of MPK3 and MPK6 kinases on the chloroplast architecture and function induced by cold acclimation in Arabidopsis.

Exposure to low, non-freezing temperatures develops freezing tolerance in many plant species. Such process is called cold acclimation. Molecular changes undergone during cold acclimation are orchestrated by signalling networks including MAP kinases. Structure and function of chloroplasts are affected by low temperatures. The aim of this work was to study how the MAP kinases MPK3 and MPK6 are involved in the chloroplast performance upon a long period of cold acclimation. We used Arabidopsis thaliana wild type and mpk3 and mpk6 mutants. Adult plants were acclimated during 7 days at 4 °C and then measurements of PSII performance and chloroplast ultrastructure were carried out. Only the mpk6 acclimated plants showed a high freezing sensitivity. No differences in the PSII function were observed in the plants from the three genotypes exposed to non-acclimated or acclimated conditions. The acclimation of wild-type plants produced severe alterations in the ultrastructure of chloroplast and thylakoids, which was more accentuated in the mpk plants. However, only the mpk6 mutant was unable to internalize the damaged chloroplasts into the vacuole. These results indicate that cold acclimation induces alterations in the chloroplast architecture leading to preserve an optimal performance of PSII. MPK3 and MPK6 are necessary to regulate these morphological changes, but besides, MPK6 is needed to the vacuolization of the damaged chloroplasts, suggesting a role in the chloroplast recycling during cold acclimation. The latter could be quite relevant, since it could explain why this mutant is the only one showing an extremely low freezing tolerance.

Addressing Syndemic Health Disparities Among Latin Immigrants Using Peer Support.

The purpose of this project was to develop a multidimensional understanding of synergistic connections between food-related and emotional health in the lives of Latina immigrants using a community-engaged approach with women who participate in a social isolation support group. The domains of interest included the intersection of social isolation, depression, diabetes, and food insecurity. We tested an innovative "structured dialogue" (SD) approach to integrating the domains of interest into the group dynamic. We documented key positive impacts of participation in the group on women's everyday experiences and emotional wellbeing. We demonstrated the extent to which this approach increases women's knowledge of food and food resources, and their self-efficacy for dealing with diabetes and food insecurity.

Iatrogenic Spinal Epidural Hematoma in the Acute Postoperative Period.

BACKGROUND: Spinal epidural hematomas (SEHs) are a rare but serious complication associated with spinal surgery, with an incidence estimated to be as high as 3%. Patients present with back pain and neurologic symptoms, with a typical onset time of several hours to days following surgery. CASE REPORT: A 60-year-old female who underwent cervical spine surgery had negative intraoperative neuromonitoring and no apparent neurologic deficits of the upper extremities immediately postsurgery. On arrival in the postanesthesia care unit, the patient reported a loss of sensation in her lower extremities, prompting the anesthesiology resident to perform a focused neurologic examination. The patient demonstrated 0/5 motor strength in the lower extremities and total loss of sensation to touch and temperature up to the level of T10 bilaterally. She was returned to the operating room, and surgical exploration revealed a cervical SEH. Decompression yielded abrupt return of motor evoked potentials and improvement in somatosensory evoked potentials. CONCLUSION: As the primary clinician in the perioperative period, the anesthesiologist is ideally positioned to be the first to detect any deterioration in a patient's condition. Anesthesiologists should be cognizant of the potential for acute presentation of SEH so that it can be considered in the differential diagnosis.

Inclusion of special populations in clinical research: important considerations and guidelines.

BACKGROUND: Trials that involve human participants call for experiments or observations that are performed in a clinical research setting. Currently, there are over 16,000 clinical trials open in the United States. Despite continuing efforts to include "special populations" in clinical trials, there are gaps in participation for people who are either minors or elderly adults, are from historically under-represented minorities, or live in rural communities. The inclusion of these special populations in clinical trials research is essential for conclusions that benefit all populations. Data suggest that study partic-ipation rates for special populations have fallen to levels that could endanger the successful performance of some types of research. This is particularly concerning in the 21st century, where demographic trends in the United States continue to shift towards an older and Hispanic population with fewer rural dwellers. Trends in New Mexico and other minority-majority states mirror many of these shifts. RELEVANCE FOR PATIENTS: In this review, we highlight improvement strategies for enhanced clinical trial participation by members of special populations. Key drivers for disparate clinical trials participation and outcomes often include differences in genetics, physiology, and perceptions of mistrust towards researchers. To overcome these barriers, we focus on best practices in recruitment strategies from the perspectives of the participants, the researchers and the institutions that support clinical trials.

A Comprehensive Approach to Community Recruitment for Clinical and Translational Research.

INTRODUCTION: Recruitment and engagement for clinical and translational research is challenging, especially among medically underserved and ethnic or racial minority populations. METHODS: We present a comprehensive model developed through the Clinical and Translational Science Center at the University of New Mexico Health Sciences Center that addresses three critical aspects of participant recruitment. RESULTS: The components of the model are: 1) Recruitment from within UNM to UNM-centered studies, 2) recruitment from within UNM to community-based studies, and 3) recruitment from outside UNM to UNM-centered studies. CONCLUSIONS: This model has increased research participant recruitment, especially among medically underserved populations, and offers generalizable translational solutions to common clinical and translational research challenges, especially in settings with similar demographic and geographic characteristics.

Health Extension and Clinical and Translational Science: An Innovative Strategy for Community Engagement.

Health Extension Regional Officers (HEROs) through the University of New Mexico Health Sciences Center (UNMHSC) help to facilitate university-community engagement throughout New Mexico. HEROs, based in communities across the state, link priority community health needs with university resources in education, service, and research. Researchers' studies are usually aligned with federal funding priorities rather than with health priorities expressed by communities. To help overcome this misalignment, the UNM Clinical and Translational Science Center (CTSC) provides partial funding for HEROs to bridge the divide between research priorities of UNMHSC and health priorities of the state's communities. A bidirectional partnership between HEROs and CTSC researchers was established, which led to: 1) increased community engaged studies through the CTSC, 2) the HERO model itself as a subject of research, 3) a HERO-driven increase in local capacity in scholarship and grant writing, and 4) development of training modules for investigators and community stakeholders on community-engaged research. As a result, 5 grants were submitted, 4 of which were funded, totaling $7,409,002.00, and 3 research articles were published. Health extension can serve as a university-funded, community-based bridge between community health needs and Clinical and Translational Science Award (CTSA) research capacity, opening avenues for translational research.
